City Security Services was formed in 1993. Our current shareholders purchased the business in 2020 and we have subsequently made the acquisition of GR8 Security, Pacesetter Members in their own right. This is part of an ambitious growth plan to further increase our footprint and capability.

We are investing into our technology platforms to increase both operational and administrative capability and efficiency, enabling our Managers to spend more time on site with our clients and our staff.

Our vison is “To make your Security our Priority”.

The most important people in our organisation are the front-line staff, delivering our services. We aim to be an employer of choice and to achieve excellent service through trained and motived staff, empowered to deliver to our clients.
